CVE-2026-60820Network attack vector

Unauthenticated data compromise via undisclosed REST flaw

Published Aug 18, 2026 · Updated Aug 20, 2026

Improper input validation in Oracle Siebel CRM Integration 17.0 through 26.6 allows remote attackers to read and alter data via HTTP. Oracle identifies the REST component and a quantity-validation weakness but has not published the affected code locus or its incorrect operation on input. Exploitation requires no credentials or user interaction but has high attack complexity and grants access to create, delete, modify, or read critical accessible data.
